UK makes U-turn decision on Huawei after US pressure

Written on Tuesday, 14 July 2020 13:09

Huawei has called on the UK government to reconsider a ban on the purchase of its 5G equipment, saying London had reacted to pressure from Washington rather than security concerns.

The Chinese telecoms giant's UK spokesman Ed Brewster called the move "disappointing", adding: "Regrettably, our future in the UK has become politicized, this is about US trade policy, not security."

Britain's digital minister Oliver Dowden announced in parliament that it approved the phased removal of Chinese technology giant Huawei from the country’s 5G network, after Prime Minister Boris Johnson chaired meetings with his Cabinet and the National Security Council.

The policy reversal hands a major victory to US President Donald Trump's administration in its geopolitical and trade battle with China.

However, it threatens to damage Britain's relations with the Asian power and carry a big cost for UK mobile providers that have relied on Huawei equipment for nearly 20 years.

In January Britain said that Huawei equipment could be used in its new 5G network on a limited basis. Since then, Prime Minister Boris Johnson has faced growing political pressure domestically to take a harder line against Beijing, and in May the United States imposed new restrictions to disrupt Huawei’s access to important components.

"Given the uncertainty this creates around Huawei's supply chain, the UK can no longer be confident it will be able to guarantee the security of future Huawei 5G equipment," Dowden said.

"From the end of this year, telecoms providers must not buy any 5G equipment from Huawei," he told lawmakers.

The new guidelines also require all existing Huawei gear to be stripped out by the end of 2026.

Nokia today announced the availability of a software based upgrade that will enable its 4G/LTE radios to be migrated seamlessly to 5G/NR.

These features will have a high value to Nokia’s customers as they provide immediate support for approximately one million radios, reaching 3.1 million by the end of the year and over 5 million in 2021. By upgrading existing radio elements via software, Nokia is helping to streamline the process of refarming 4G/LTE spectrum into 5G/NR. The move will also support existing customers and the installed base by offering a seamless and cost-effective upgrade path to 5G/NR.

Most of the 5G/NR deployments to date have been performed with TDD cmWave and TDD mmWave deployment but the next big wave of 5G/NR rollouts will be delivered by refarming existing FDD bands to 5G/NR. TDD spectrum benefits from enlarged coverage and capacity when combined with already deployed FDD network infrastructure and spectrum bands via TDD/FDD Carrier Aggregation.

The ability to upgrade 4G/LTE radios via a software update will significantly smooth out the deployment of 5G/NR FDD, avoiding costly and disruptive site visits. Nokia has a vast customer base of 359 4G/LTE customers with deployed FDD RF units most of which are possible to upgrade. This will provide a new and smoother way for operators to build 5G/NR coverage in lower bands via spectrum refarming. Nokia’s 4G/LTE radios are market leading and outperform all vendors according to independent testing.

Nokia also has Dynamic Spectrum Sharing (DSS) already in live networks covering 2G/GSM-3G/WCDMA-4G/LTE and recently introduced DSS for 4G/LTE-5G/NR. This capability completes a DSS solution, covering all access technologies and making the radio frequency refarming to 5G/NR a simple and efficient process.

In a typical case DSS will be introduced to one or few 4G/LTE bands which are then combined with carrier aggregation between other bands running pure 4G/LTE or 5G/NR. Nokia has the market leading DSS solution covering all radio access technologies from 2G/GSM to 5G/NR.

Nokia estimates that this solution will save the telecommunications industry potentially tens of billions of euros in site engineering and re-visit costs as communication service providers are able to upgrade their networks to 5G/NR on FDD with software.  

Chris Nicoll, Principal Analyst at ACG Research, said, "While Open RAN promises software upgradability to ease transitions between ‘Gs’ and add new features, Nokia’s Flexi and AirScale portfolio shows it is ahead of the game by providing a software upgrade to transition over 5 million 4G radios to 5G. Efficient FDD spectrum refarming is critical for fast, broad and deep 5G deployments. With Nokia supplying the majority of the world’s top 4G operators, supporting key advanced features such as DSS helps those operators lead with 5G.”

 “We already provide market- leading LTE radios to hundreds of customers around the world. This is an important solution because it will help our customers, quickly and efficiently upgrade their existing LTE radios so that they are 5G ready saving them time and money.”

UK set to phase Huawei out of 5G networks

Written on Tuesday, 07 July 2020 05:05

Britain is set to phase out Huawei equipment from its 5G mobile networks this year, the U.K. press has reported. If so, it marks a major U-turn in the government’s position on the Chinese telecommunications giant.

The government is drawing up plans to strip Huawei gear from Britain’s next-generation networks by the end of the year, The Sunday Times and The Daily Telegraph newspapers reported. 

It comes after London said in January that Huawei could play a limited role in Britain’s 5G networks, a move which angered the U.S. as it sought to get other countries to block the Chinese company.

Washington maintains that Huawei is a national security risk, alleging its equipment could be used by Beijing for espionage. Huawei has repeatedly denied the claim. 

The apparent policy reversal was driven by a new report from a branch of British intelligence agency GCHQ that raised new security fears over Huawei following U.S. moves to cut off the Chinese firm from key chips.

China's ambassador to Britain has warned that London faced a risk to its international reputation if it blocked Huawei from the nation's 5G network.

The Financial Times said the government will decide this month to phase out the Chinese technology giant's equipment because of persistent concerns about spying.

A UK security investigation, yet to be published, has raised "very, very serious" questions over Huawei's limited 5G role in Britain, the newspaper added.

Culture Secretary Oliver Dowden said separately he had received the National Cyber Security Centre report and there would be a "significant" impact on Huawei's 5G role.

But Beijing's top envoy in London, Liu Xiaoming, described Huawei's involvement as a "win-win" for both the company and UK-China relations.

"We have tried our best to tell the story of Huawei but we can't control the British government decision," he told a news conference.

However he warned that if Huawei was rejected, it could impact Britain's international standing and erode the trust of other existing or potential overseas investors.

He suggested it would be an example of Britain succumbing to "foreign pressure", in a clear reference to Washington's position on Huawei.

British Prime Minister Boris Johnson is under intense pressure from the US, and members of his own ruling Conservative Party, to cut ties with Huawei.

US officials argue that the company could spy on Western communications or simply shut down the UK network under orders from Beijing - a charge the company denies.

Huawei's position has been complicated further by Washington's decision to roll out a new wave of sanctions to cripple the company's production of the chips used in 5G.

The FT said Johnson was drawing up plans to remove the Huawei technology from Britain's 5G network after warnings that the US sanctions could curtail the company's access to American semiconductors and force it to use riskier supplies.

Ambassador Liu rejected claims China was a "hostile country".

"We want to be your friend, we want to be your partner but if you want to make China a hostile country you have to bear the consequences," he added.

Cisco and Rakuten have adopted the world’s first end-to-end fully virtualized cloud-native mobile network.

Cisco played a key role in the development and deployment of the cloud-native virtualized architecture which is currently being used by Rakuten Mobile. Cisco has said that its state-of-the-art highly-automated approach has gained great traction amongst some of the world’s leading telecom operators.

According to Jonathan Davidson, SVP and GM, Cisco Mass-Scale Infrastructure, telecom operators across the world have been investing “30 to 40 billion dollars a year in deploying radio access technology and we still have so many parts of the globe that do not have coverage or do not have decent coverage… This is something that can be transformed with this new approach that Rakuten Mobile has pioneered. You could definitely call it profound.”

Davidson has also predicted that it will be widely adopted in Japan. Adding that, “this is just the beginning. Now we need to get to 5G and we need to scale the infrastructure.”

Cisco has not only supplied them with the IP internet protocol (IP) routers which essentially transport traffic from Rakuten’s radio towers and the cloud radio access network (RAN) into the IP core, but the Telco is also providing them with management orchestration software.

Rakuten Mobile’s CTO, Tareq Amin, stated, “Cisco is playing a crucial role in stitching together the carious elements of our new network.”

“The design approach we mapped out with Cisco is enabling us to deliver high-value services at very affordable prices, enabling our customers to really benefit from our cloud innovation. Scaling of such orchestration function is a challenge,” he continued.

Davidson says that he expects Rakuten Mobile’s network to perform at a very high level due to its software-defined architecture which allows for the fine-tuning of its network in real-time.

 “Any time you do something that has never been done before, there are going to be a lot of challenges that you have to uncover. It always come back to the team and making sure the team is aligned to a joint vision and a joint mission. Tareq is a phenomenal visionary who has got companies that have traditionally been competitors to collaborate and partner in new ways to really achieve something that has not been achieved before,” said Davidson.

In terms of the technology’s performance, there are technical and operational advantages that come to play. In fact, Cisco expects other operators to follow suit and deploy cloud-based RAN.

Nokia today announced its WaveFabric Elements portfolio of photonic chips, devices and subsystems, including its fifth generation coherent digital signal processor family, the Photonic Service Engine V (PSE-V). 

The explosion in video and mobile bandwidth demand over the past decade has been met through the continual advancement of optical and silicon technology. But as fundamental limits of transmission capacity and processing power are approached, network operators will need new ways to continue to scale their networks to meet the surging demands of 5G and cloud networking, while containing cost. Key to this transition is 400 Gigabit Ethernet (400G) technology.

Set to become the pervasive network interface across IP, optical and data center networks, 400G marks the first common data rate since the introduction of 100G approximately 10 years ago.

As the foundational technology for high bandwidth transport, the critical task of electro-optics in the coming years will be to transport 400G services at the lowest cost across a wide range of networking applications, each with distinct size, power, and performance requirements.

Nokia’s WaveFabric Elements portfolio combines digital signal processing (DSP) and optics technologies focused on emerging end-to-end 400G applications, allowing Nokia to optimize the entire electro-optic engine that powers today’s networks and the transformational upgrades to come.

This high degree of vertical integration ensures that Nokia’s optical solutions will meet the unique economic and technical requirements of data center, metro, long haul, and subsea networks.

Nokia’s fifth generation coherent DSP family, comprising the high-performance Nokia PSE-Vs (super coherent) and the low power PSE-Vc (compact), continues Nokia’s history of developing multiple DSPs optimized for different optical networking applications, form factors, and platforms.

The new DSPs are complemented by the CSTAR portfolio of coherent optical engines brought to Nokia via its recent acquisition of Elenion Technologies, a pioneer in silicon photonics. A new family of pluggable transceiver modules allows Nokia to address their critical and expanding role in data center, IP and optical networks, as well as emerging markets and applications highly dependent upon low-cost optical connectivity, such as access and mobile networking.

Sam Bucci, Head of Optical Networks at Nokia, said, "Networks are truly at an inflection point, and 400G will be a catalyst for a significant transformation. With our WaveFabric Elements portfolio, Nokia is committed to supplying the 400G optical ecosystem with components, subsystems and design services, as well as continuing to build the highest performing optical transport solutions for the 400G era and beyond."

Scott Wilkinson, Lead Analyst at Cignal AI, said, "Nokia is one of a select few companies with the experience of building five generations of DSPs. The company’s expertise in vertical integration is a key competitive advantage in the battle for next generation coherent solutions. The focus on 400G transport in the PSE-V is well-positioned for market needs."

The CSTAR family of optical engines is currently shipping to customers. PSE-V-based platforms and pluggables will be available beginning in Q4 2020. 

The Nokia WaveFabric Elements portfolio addresses the demanding power, performance, and cost-per-bit requirements of 400G networking across data center, metro, core and subsea applications.

The PSE-Vs, which can run up to 90 Gbaud, employs the second generation of the industry’s only field-proven implementation of Nokia Bell Labs-pioneered probabilistic constellation shaping (PCS). Combining refined algorithms with the enhanced capabilities of a new generation of silicon, it is capable of transporting up to 800G, while providing 60% greater reach, 40% lower power per bit, and 15% greater spectral efficiency than previous DSP generations.

The PSE-Vc enables programmable capacity from 100G to 400G with metro to long haul capability. Its extremely low power enables integration into a variety of pluggable transceiver modules.

The Nokia CSTAR family of optical engines leverages state-of-the-art silicon photonics and packaging technology, and addresses applications, including intra-data center, metro DCI and long-reach optical transport. Paired with PSE-V DSPs within Nokia platforms, they are also available independently to industry partners for integration into pluggable transceiver modules available to the broader market.

Nokia’s 400G pluggable coherent transceiver modules are optimized to address a range of platforms and applications, including Nokia’s broad portfolio of optical transport, IP, fixed access and mobile solutions. The portfolio includes 400G ZR/ZR+ capabilities in the QSFP-DD form-factor and a higher performance, more feature rich 400G multi-haul variant in a CFP2-DCO form-factor.

Aimed at building an intelligent and simplified network, enhanced customer experience, protecting network investment, and addressing customized industry requirements, the solution is expected to be an important force for industry-wide digital transformation.

Huawei was the first in the industry to propose 5G deterministic networking in May 2019. The company joined hands with industry partners to establish a 5G deterministic network industry alliance at the Shanghai MWC in June, 2019. The alliance today has more than 100 member organizations and has carried out cross-industry collaboration based on 5G deterministic networking in the fields of multimedia, manufacturing, energy, healthcare, and connected vehicles.

A growing range of projects showcasing the success of the emerging 5G ecosystem include:  Smart Port (in Shanghai), Smart Grid (partnering with China’s State Grid and China Southern Power Grid), Smart Factory (partnering with Qingdao Haier), an AR-based cultural tourist attraction "Wonderland of Mountains and Rivers " (for Beijing World Expo), and AR advertising (for Shenzhen Airport).

Huawei and industry partners, including the China Academy of Information and Communications Technology (CAICT), China Mobile, China Telecom, and China Unicom, jointly released a 5G Deterministic Network Industry White Paper in February, 2020. This is the first time 5G Deterministic Networking has been introduced comprehensively, including its definition, concepts, key technologies, and successful use cases. This release opens a new chapter for 5G development, promotes development of further network applications, and puts 5G at the center of industry digitalization.

Huawei has been committed to developing the core network section for years and has made significant contributions to the industry’s development. The service-based architecture (SBA) jointly proposed by Huawei and China Mobile has become the unified 5G network architecture. Huawei earned an overall leadership position, with Leader rankings across all the evaluated criteria in the GlobalData's 5G Core competitiveness ranking report.

Huawei also won the "Best 5G Core Network Technology Award" at the 5G World Summit in 2019, and was the first to be granted the 5G Core Network Telecommunication Equipment Network Access License in China. Huawei will continue to drive progress to better serve customers and promote the rapid development of 5G.

Nokia, along with leading operators Telenor and Telia, announced that it has deployed the world’s most advanced shared wireless network supporting a Multi-Operator Core Network (MOCN) feature, enabled for wireless technologies spanning 2G to 5G.

The 5G MOCN feature was deployed on a trial network in Denmark and verified with successful end-to-end test calls. MOCN, the most advanced network architecture model allowing for network sharing, enables distinct mobile operators with their own core network to share a common radio access network infrastructure as well as spectrum resources.

This is the first network to include live MOCN capabilities for 2G, 3G, 4G and 5G simultaneously. The live trial utilized Nokia’s end-to-end 5G technology, including 5G RAN and 5G cloud core.

Network sharing is an efficient and cost-effective way for two or more mobile operators to build and roll out a network at scale without having to duplicate efforts. It is an important strategic consideration for operators that helps them to quickly deploy 5G networks to consumers and businesses while keeping costs to a minimum. As 5G networks require a higher density of radio equipment, such as small cells, to deliver the right performance and coverage, network sharing results in overall lower power consumption compared to individual networks.

Tommi Uitto, President of Mobile Networks at Nokia, said: “Deploying 5G networks independently can be an expensive undertaking for mobile operators in the most competitive markets. This trial highlights that through network sharing, operators can drive efficiencies, lower costs and bring the myriad benefits of 5G to businesses and consumers quickly. We hope that this trial demonstrates to operators around the world that there are multiple options open to them to get their 5G networks up and running quickly and at the lowest possible cost.”

Georg Svendsen CTO at Telenor, said: “Network sharing is a clear strategic priority for Telenor to continuously deliver one of the best mobile networks in the world, supporting safe and reliable connectivity to our private and business users.”

Henrik Kofod CTO at Telia Denmark, said: “This is a major step on our 5G journey, and I really look forward to start testing with real customers and understanding how 5G can provide true value for them. I hope this will inspire other operators in the Danish market to move in the same direction. Network sharing is a great choice when it comes to building sustainable 5G networks. When we maximize our resource utilization, we lower our carbon footprint and optimize our investments.”

Ericsson launches spectrum sharing software

Written on Wednesday, 04 March 2020 07:17

Ericsson has announced that its unique dynamic spectrum sharing solution is commercially available, allowing communications service providers to quickly and cost-effectively launch 5G on a nationwide scale.

Ericsson Spectrum Sharing enables both 4G and 5G to be deployed in the same band and on the same radio through a software upgrade and dynamically allocates spectrum based on user demand on a 1 millisecond basis. Ericsson’s dynamic spectrum sharing is the most economically feasible way to deploy 5G on existing bands – enabling wide 5G coverage from day one – making more efficient use of spectrum and enabling superior user performance.

Fredrik Jejdling, Executive Vice President and Head of Networks, Ericsson, said, “For the first time, our customers do not have to re-farm spectrum before deploying a new ‘G’ and can quickly get 5G on the same footprint as they have with 4G today. In the next 12 months, more than 80 percent of the commercial 5G networks we support will use our spectrum sharing solution to achieve broad 5G coverage.”
“Spectrum is a scarce and costly resource that should be used efficiently. Ericsson Spectrum Sharing will mean that service providers can rapidly roll out 5G on their FDD bands without the need to re-invest. It means they can use both their new and existing bands for 5G high-speed, high-capacity services. Dynamically allocating spectrum between 4G and 5G is going to be the best way to start deploying 5G,” said Julian Bright, Senior Analyst, Ovum/Omdia.
